1 / | | 1 | ------- dy | 2*y + 1 | / 0
Integral(1/(2*y + 1), (y, 0, 1))
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
The integral of is .
So, the result is:
Now substitute back in:
Now simplify:
Add the constant of integration:
The answer is:
/ | | 1 log(2*y + 1) | ------- dy = C + ------------ | 2*y + 1 2 | /
log(3) ------ 2
=
log(3) ------ 2
log(3)/2
